Haven't had it happen yet in 8 years working here. Have bricked a couple Internet routers, but I think they had issues to begin with.

Some. but only when the upgrade was in progress and lost power to the device in the middle of the update.

One new Axis Q-series PTZ camera, over the course of several hundred IP camera opportunities. The power flickered during an update, and when it came back up nothing was responsive.
Axis tech support exchanged it with no problem. The person I spoke with said they could fix it and since it was new they could just restock it.
But the moral of the story: always have a UPS connected when you're upgrading firmware!
I can't think of an occasion where I or any of the technicians I have worked with has bricked a camera, DVR, or NVR during a firmware update to the point that it was irrecoverable. It is always of concern particularly when done over a network. We do have some NIDs that have been particularly worrisome, but it has a "brickbreaker" recovery mode. I have seen some devices bricked for various other reasons not pertaining to firmware though.
I have personally worked with and supported over the phone upgrading thousands of cameras over the years. I can attest to only a handful of camera that have been bricked. Sometime, you can default the camera, and/or send the firmware to the again. I have seen cameras that have a "safe mode" allowing you to send the firmware again.
On rare occasion, maybe 3 or 4 cameras have they needed to be sent for service to get them operational.
It has happened to me just once when I was updating a Bosch VIP X1600-XF encoder.
